I personally would not get involved with any technology as old as the Q4C. I worked in a factory that had about 20 of those and was not impressed. It seemed like there was always some problem (electro/mechanical) and their service was not "world cl

I'm looking for comparison data on MTBF for solder joints meeting IPC Class II vs Class III.

MA/NY DDave, I'll take your money. I'm betting on the Class II, whatever that is, because: * Solder is the same. * Board is the same from a fabrication and probably materials standpoint. * Components are the same. * Processing is the same. ... but

Has anyone seen or put together a good collection of proper handling procedures for components and PCB's? I realize a lot of it is no-brainer stuff, but I need some depth for a training class we are putting together. This would include ESD, Moisture

You can have a look at Assembleon (formerly PHILIPS EMT) equipment. They have equipment ranging from rated speeds of 6500cph to 150,000cph. I guess their OPAL XII should be the best fit machine in terms of its capability and speed both. It can do fro

J-STD-001C just requires that the area not be so dirty as to contaminate your product, tools, workspace, etc. If you start counting particles, you're into cleanroom territory. Do a search on ISO 14644-1 for specifics. Actually Wikipedia does a ni

We've got a problem with a fine pitch board that has about .005" registration error at each end (towards the center of the board) when it's printed. Apparently we've got a case of board stretch generated at the fab shop. I still have to do some mea

The use of booties isn't required per se, just considered a standard step necessary to reach the 10,000 target. You also need to vacuum (central vac system, NOT exhausting into the room) daily, mop weekly, have a one piece floor, blah, blah, blah....

Sr. Tech, you are right in that there is no verification of the profile. We are a Class 3 high mix OEM. We have visual inspection after SMT. We have not seen problems with wetting, grainy solder, cold solder, charred boards, etc. that would indicate
